Autoit Adobe aerender - command-line

Question

I am rendering an Adobe After Effects Project with Autoit and aerender,
I put this line of code in the console:
aerender -project C:\aeProjects\projekt_1.aep -comp "Main" -output C:\aeProjects\output\asd.avi
Now how can I check if this proccess is done, so that I can resume safely other steps.
At the moment I just put a sleep but that is not a good practice I think.

You can use the ProcessExists function to do this.
Here is a simple example with a timeout option:
MsgBox(64, "RunCmdWait", RunCmdWait("notepad.exe"))
Func RunCmdWait($sRuncmd, $iTimeout = 10000)
Local $iPid = Run(#ComSpec & " /c " & $sRuncmd, #ScriptDir, #SW_HIDE, 6)
Local $hTimer = TimerInit() ; Begin the timer and store the handle in a variable.
While 1
Sleep(250)
;Returns 0 when the process is closed
If ProcessExists($iPid) = 0 Then
SetError(0)
ExitLoop
EndIf
;Returns 1 on time out error
If TimerDiff($hTimer) >= $iTimeout Then
SetError(1)
ExitLoop
EndIf
WEnd
Return #error
EndFunc ;==>RunCmdWait
Here is a example with StdoutRead if you need to read the output:
MsgBox(64, "StdoutRead", GetStdoutRead("dir"))
Func GetStdoutRead($sRuncmd)
Local $iPid = Run(#ComSpec & " /c " & $sRuncmd, #ScriptDir, #SW_HIDE, 6)
Local $sStdoutRead = ""
While ProcessExists($iPid)
$sStdoutRead &= StdoutRead($iPid)
WEnd
Return $sStdoutRead
EndFunc ;==>GetStdoutRead
